SLDERINGTOOL.

SPECIFICATION forming part of Letters Patent No. 462,607, dated November3, 1891.

Application tiled February 20, 1891. Serial No. 882,224. (No model.)

To a/ZZ who/1t it may concern:

Be it known that I, CHARLES L. WAGANDT, a citizen of the United States,residing at Ilaltimore city, State of Maryland, have invented certainnew and useful Improvements in Soldering-Tools; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My present invention is directed to an economy in soldering-tools and inthe use thereof in three important particulars: first, in the quantityof gas required for a given amount of work, which quantity is by myinvention materially reduced; second, in the consumption of the copperor soldering block, which I completely utilize, third, in the rapiditywith which seams can be run and consequent econ'- omy of the workmanstime, resulting from the high degree of heat which can be maintained inthe copper and :from the general efficiency of the tool.

lVith such objects in View my invention consists in t-he parts andcombinations thereof hereinafter more particularly described andclaimed; but it will be understood. that my improvements are not limitedin their application to that construction which, for the sake ofillustration, I have set forth.

In order to make my invention more clearly understood, I have shown inthe accompanying drawings one practical means for carrying the saineinto effect. l

In said drawings, Figure] is a sectional view of a soldering-toolembodying my improvements. Fig. 2 is a front view of the same. Fig. 8 isa transverse section on line 3 3 of Fig-.1. Fig. t is a perspective viewof the combined holder and gas-chamber. Fig. 5 is a sectional View, on alarger scale, of the swivel-joint for the gas-pipe. Fig. (l illustratesby side view the application of the invention to the holding andheating' of another form of copper.

I may here remark that while my invention is especially adapted for usein floating or bottom irons, so called, it is also available inseaming-irons.

Referring to the drawings, A indicates the combined holder andgas-chamber, provided with a through longitudinal aperture or seat a,into which the copperbar or blockis adapted to be introduced and inwhich it is longitudinally adjustable.

A is a combustion-chamber or space, which occupies the center of theholder A and when the copper is in place surrounds the latter. Thisspace is then divided into what may be termed a top chamber a', two sidechambers a2 a2, and a bottom chamber a3.

ct'l is an end gas-supply opening above the aperture u. and entering thechamber a in the direction parallel with said aperture. The top of theholder is preferably furnished with a swell or enlargement toaccommodate this opening and the opening screw-threaded to receive thegas-pipe.

c6 is a flame or heat vent opening from the bottom chamber ct and in theend olf the holder opposite to that in which the supply opening a" isformed. This vent is immediately contiguous to or forms a part of theaperture u, so that the issuing flame and heat plays along and upon theunder face of the copper.

aTindicates one or more Ventilating or lighting openings into the rearof the chamber A to aid the ignition and combustion of the gas.

The holder thus described may be employed with any suitable copper orsoldering block and may be variously supported or handled.

In the construction shown Bis a solderingcopper of uniform cross-sectionand adapted to lill the aperture c, and C the gas-supply pipe and handleadapted to be screwed into the opening at. The handle and copper thuslie parallel with each other, and the tool is adapted for use as afloating or bottom iron, while the c opper is at the same timeunlimitedly adjustable or at least adjustable to a degree limited onlyby its own length, its longitudinal position in the holder not beingrestricted either by the holder itself or by the handle. I am thereforeable, first, to provide a floating-iron for which the coppers may bemade of any desired length; second, to apply the heat at a pointimmediately contiguous to thesoldering-edge and there only Whatever bethc length of the copper, and, third, to consume and utilize practicallythe entire copper before discarding it. By adjusting the soldering-edgeof the copper to a point close to t-he vent a I am able to obtain thehighest degrec of heat thatcan be desired, and the Work- ICO tio

man can llow the solder and run seams with great rapidity.

Heretofore it has generally been the practice to secure the copper inthe holder by one or more set-screws. I have found that in asoldering-toolsuch securing means is not at all durable. The high degreeof heat to which the parts are subjected, combined with the use of theset-screw, soon disintegrates the screwthreads and prevents the secureadjustment of the copper. Another frequent caiisev'hich renders thetools useless and which is incident to the use of set-screws is thatwhen highly heated and softened the screws are often twisted off in theeffort to clamp the copper. The device is then useless until the remainsof the screw are drilled out from the holder.

I have provided the holder above described with a longitudinally (orlaterally) operating wedge D, for which a seat as is formed in theholder, this seat constituting an enlargement of the seat or apertureci. The Wedge is provided with a handle d by which it may be withdrawn.lVhen in place it bears upon one face of the copper and presses'thelatter firmly against the opposite side or bottom of the holder.

In order to facilitate the manipulation of the tool7 the upper end ofthe handle and gas-tube C is connected with the flexible rubber gas-pipeC (through which a suitable mixture of air and gas is fed in the usualmanner) by means of a swiy'ehjoint. This joint comprises aninternal]y-screw-threaded coupling-nut N, adapted to screw tightly uponthe upper externally-threaded end of the tube C or upon an interposedbushing and provided With an end flange n and a nipple P, adapted to fitclosely but smoothly and so as to rotate Within the end of the tube C,having a peripheral shoulder p, adapted to abut the inner face of theflange mand a reduced portion p', passing through the outer end of thenut N and tightly or rigidly connected with the rubber tube C. There isthus provided a smoothly-workingr swivel-joint, the escape of gasthrough which is precluded by the fit of the nipple P Within the tube Cand the fit of the shoulder p against the flange'oz. Vith regard to theheating .'of the copper it will be observed that the end which is to beused only, and not the Whole copper, is raised to the high Workingtemperature.

Having thus described my invention, what I claim isl. In asoldering-tool, a combined gas-chamber and holder for the copper orsoldering` block, having therethrough a longitudinal aperture 0r seatfor the copper, an end gas -supply opening above and parallel with saidaperture, a combustion chamber or space surrounding the space occupiedby the copper, and an end dame or heat-Vent opposite to the saidsupply-opening, substantially as set forth.

2. In a soldering-tool, the combination of a gas-chamber and holderhaving a supplytube connected therewith and having an aperturetherethrough and a copper passing entirely through said aperture andlongitudinally adjustably therein, the rear portion of said aperturebeing closely fit-ted and closed by the copper and the forward portionof said aperture being enlarged for the exit of gas and flame,substantially as set forth.

3. The combination of theholder, the soldering-block, the gas-supplytube, the flanged nut N, the nipple P, itting Within the tube and havingthe shoulder p, and the eXible pipe secured to the outer end ot' thenipple, substantially as set forth. l

fl. In a soldering-iron, the combination of the combined holde'r andgas-chamber having an aperture therethrough and a seat aS formed in theside of the aperture, the gassupply pipe connected to the chamber, thecopper passing through said aperture, and

the securing-Wedge fitting and closing said,

seatl and substantially flush with the wall of the aperture,substantially as set forth.

In testimony whereof I affix my signature in the presence of tWoWitnesses.
